I tried that and it works for a single dimension but if you add a second dimension, you get an error: non-constant expression as an array bound. Here is what I tried and had fail:
int a = 5; int b = 6; int *array; array = new int[a][b]; ... It fails at the array = new int[a][b] line because it wants a constant.

Here's how to do the dynamic arrays: int a = 5; int *array; array = new int[a]; // use the array array[0] = 4; delete [] array; This link shows one way of doing a multidimensional array on the heap: http://www.parashift.com/c++-faq-lite/freestore-mgmt.html#faq-16.16 -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
